FAQ

Frequently asked questions

How much water do the waterers hold?
Yearan offers livestock water tanks that hold as little as 15 L and as much as 450 L of water.
What are the waterers made of?
Double-wall rotationally molded polyethylene — strong and corrosion-free. One-piece designs are completely sealed, protecting the foam insulation from moisture, with UV inhibitors for lasting color and longer life.
What is your warranty?
We offer a 10-year limited warranty on our livestock water tanks and a 2-year warranty on component parts such as internal floats, valves and heaters.
What keeps the water from freezing?
Foam insulation and a sealed closure flap keep Energy-Free (NG) units frost-free in all but the coldest climates. For harsh winters, our Electric Waterers with a submersible heating system are recommended.
Are all waterers insulated?
All our waterers feature foam insulation except for our WB Series.
Why does my waterer leak?
Tank floats are not pre-set — adjust the float to your desired water level after installation. Water lines over 55 psi require a pressure reducer.
Are the waterers available in other colors?
They come standard in our signature green, but you may special-order by the truckload in a limited palette including blue, orange and gray (additional production time required).
How do you clean the waterers?
All our waterers feature large drain plug(s) for fast, easy draining.
